invention relates to certain new and H useful improvements in railjacks, and has for its primary object the construction of a jack formoving and alining railway the primary object of which is to construct ajack with a strong fulcrum or pivotal connection between the base andlever; and further, to provide such a connection between the lever andbase that the entire device ma be carried by v out any angenof 'the basebeing "separatedfromtheleveit In the drawings: 1 Figure is asideelevation of my, improved jack, showing the device adjusted so as to beinserted under the ball of a Figure 2 is a sedt-ion takenon the use 2-2of Figure 3,

preferably cast and formed on the under rail being shown surface thereofare prongs 5 which are intended to prevent the jack from slipping whenin use. The base or support 4: is provided with upstanding side portions6 which are connected r The web 7 is substantially vertical, except theupper portion 8, Wl'llCll'lIlGllIlGS in a forward direction. Formed ineach of the upstanding side portions 6 are circular bearings 9, andrearwardly inclined slots or openings 10 which lead into said bearings.

Formed in the forward projecting portion 8 is a curved bearing 11 havingthe same degree of curvature as the bearings 9. The bearings 9 in eachof the upstanding portions 6 and ous bearing throughout the width of thesupport. 12 indicates a lever which has a hollow portion 13 into which ahandle 14 is inserted. with a shoulder 15 which is adapted to engagetheball of the rail, as illustrated in dotted lines in Figure 2. Formedforward of the shoulder 15 are a series of smaller shoulders 16, 17 and18; The shoulders 15 and 16 are especially designed to engage rails,

Theseflattened portions are "of the width of the inclined slots10;

In assembling "the le've'r with the "bas'e'of support,

into theopenings 10. In order to remove the lever from the base orsupport, the lever must be adjusted so that the flattened portions maybe removed through these 1n-' clined slots.

It will be seen from this construction that the entire jack may becarried by the handle, as illustrated in Fig. 1, and the support willnot become detached from the lever. Furthermore it will'be noted thatthe'transverse web 7 limits the rearward movement of the lower railengaging portion of the lever, thusv preventing the lever handle fromfalling forward onto the tracks out of the hands of the operator.

When my device is in operation, (see Fig. 2 for illustration) it will beobserved that the entire lifting strain will be first received by thearcuate bearing 20, and will be transmitted against theforwardlyincllned portion 8, and thence to the web 7,

'the web 7 being strengthened by the side portions 6. Thus it will beseen that I provlde a very strong and. serviceable jack capable ofstanding any strain encountered in alining or st-raighteningtracks.
